the idea is, that many backends offer the possibility to ask for help by 
running a command, e.g. in maxima its "? command", in octave its "help 
command" etc. This information is often quite lengthy, and would 
therefore clutter the worksheet. This is why Cantor shows this help in a 
separate panel.
Obviously being able to show help from other sources would be great as 
well, if anybody wants to implement this :)
